Nokia 7650 Proximity Sensor

Hy!
It is possible to disable the proximity sensor in my nokia 7650 with a Software Program?
Does someone know where i get it from?
Thanks Tom

I posted the same thing a long time ago, but didn't get any positive feedback... Guess the situation is still the same, sometimes in loud n noisy environments i wld also like to be able hold my cell close to my ear n use the loudspeaker.....
Cheers

Thanks for your answer.
I think it should go by software. I have Ringtonestudio installed and this application doesn't use the Sensor.
